12. that device is the culprit If the offending device uses a two prong plug or an external two prong AC DC adapter you can try reversing the plug in the socket If that doesn t work you may need to physically ground that device s chassis by connecting a wire called a strap from it to a grounded piece of metal such as rack ears Some pieces of equipment have a screw type ground post to which the strap can be connected if not you can attach some kind of metallic binding post to the case itself In addition you can minimize possible interference by planning your RF antenna audio electrical and computer cable runs so that they are as far apart from one another as possible and so they don t run parallel to one another If they have to cross try to ensure that they do so at a 90 angle that is perpendicular to one another In particular try to keep audio cabling away from external AC DC adapters If you re using the DA 5L in a fixed installation you may want to invest the time and money into creating a star ground network for all your audio devices This is by far the best technique for avoiding grounding problems It involves using a formidable ground source such as a cold water pipe or a copper spike driven into the earth A thick grounding cable is connected to that source and is then brought to a central distrib ution point from there individual cables are connected to each piece of equipment This setup also requires that you
